- Beit knownthat I., I-IERMMIfA. DAVEN- "roR'r, .a citizen of 'theUnited-.States residing 'at'Brocktom in .the 'county of Plymouth andV State of h/Iassat'zhlusetts,y have invented cer# clare thefollowing i'to besa full,- clear, and

yexact description of the invention, such as4 .Willenable othersgskillednfthe art to which it appertains to ,malr'eand use thesanre.

'- The present.- invention relatesto 'solev pressing machlnes and more particularly to that-classicisole pressingjfmchines which comprise .a shoe supporting jack fand a lsole pressingpad and .which are used t perform i the operationof layingthe sole.

l u i "The present invention 1s. illustrated'- as embodied in a sole 'pressing Lm'achine of fthe type described in the patent to Davenport,

No. 930,272, August `-3, 1909, upon which'thev v,present.invention is .anv improvement. f' VIii-the ,machine .disclosedvin the 'above pat-v sole pressing' padis then'given an upward i is laid under .pressure and the solepressing padis released-from. thefwo-rk, to separate the-removal .of the slioe'it is necessary for .the operator to. raise'his hand a'nd release the c lutchcollars, whichlflockthe jack inits l terthe operator has thejack is moved the shoe, .itis necessary for-.the operatorl to raise his hand freni V the wo'rk'to release the lifted .and correctly adj usted;

- One object of thepresent invention is to provide an improved structure in which' the sole pressingapad shall be automatically re- 'tracted from the 'werk .upon 'completion-of the sole pressmg. operation which obviatesf the necessity oj .the :operator .raising his vhands' from the workfto-release aclutchto separate` the vsolenenga'ing-partsfor the remoyal off theafshoe. n my`1 mproved 1 1 1a uppor'ting acl; is pressed down-A ns of a treadle to bring -,the sole. .ofva s oe ldthereoninto engagement with tliej'pressing`-pad, .tleisupporting jack automatically lockedinffposition, and-thechine,` the position of the-sole-pressingpad. is'

always under-the control of the foot treadle which movesthe'pad. into engagementwith the shoe, -so that if any readjustment of -t-he shoe is necessary afterthe pad is raised,

the .operator has merely 'to Iraise; his -foot .slightly from the treadle and adjust the shoe without the necessity of removing his hands" from the work to release 'a clutch, as in the machine described in vthe Davenport patent.

Another object of my invention is to provide an adjustment whereby the length of. the sole compressing stroke of the pressing pad may be varied to accommodatefor soles of 'a different character.

Still otherobjects Vof my invention are to dispense with' the use of springs for sepaA rating the sole-pressing members, to' reduce` the number .of parts, .and to make a more4 compact and stronger structure,

.` With-these objects in view, vthe present invention consists in a solelaying Amachine having its various .parts constructed and ar ran-ged as hereinafter described a'nd par- Iticularly pointed out `in lthe claims,l

A machine embodying the. present inven tion in its preferred ormj is illustrated in the accompanying drawingsQin which- 'gure l is a frontelevation olithe 'ma-f chine taken partlyinsection; Fig.' 2 is a top View of the adju-stabletoggle 'actuating 'linkg'Fig 3 is vaview taken partlyin' secv'ing the rol-ler clutch detail;V and.

i operating therewitlnfoot treadle's arranged to`,lift the sole pressin pads into engage'-l mentwith the shoes-he d'oathe jacks and power actuated rtoggles, arranged to then v en# gage the sole pressing. pads and tmove-them against the shoes to lay `their vsoles under pressure.

'Thei present machine, .like that of' tlie.

'presses to lay 'tefsoles o'nthe right and lett shoes respectively and is. preferably con- 'vfrom Ythe other shoe-to allow operator to change' the. work.

pad carrier 8 which issuitably secured toY Each shoe holding jack comprises a heel4 post 1 and a post 2 holding a toe-engaging pad. 5l`he se posts are adjustably mounted upon across-head 3. which is rigidly secured tol the upper ends of supporting rods 4 projecting upwardly from the side standards 5 which are mounted upongthe base plate 6 of the machine. The lasted shoe is held bythe supporting jack and the sole is laid by a sole pressing pad 7,mou`nted in a a cross-piece 9 slidablyheld uponthe vertical rods 4. The lower part 4of the cross- 4piece 9 is formed 'with downwardly 4pro-1A jecting ears 10 which are bored to'receive a. shaft 11 which fforms a pivotalbearing for the upper end of thebar 12 and upon whoseouter ends are loosely mounted the,

rollers 13. Thencross-piece 9, together with its pad carrier 8, is elevated by means of'.

treadle actuated -twin cams 14 which engage beneath the rollers 13. The camsv14 are rigidly secured together and pivoted to the side standards 5 at 15 and are lifted means of. a foot operated treadle 16 to which the cams areconnectedbyl a link 'bearing the cunter-weight 17. 'The construction' and arrangement of these parts is such that whenv the pad carrier and treadle'l 1Q are free, the-weight of the pad carrier bearing through the rollers 13 upon the cams 14 is. sufficient vto swing back the cams and raise the treadle, allowing the pad carrier to drop, the counter-weight 1 7 being-added to partly compensate' for the weight of the pad carrier and to'require lesspressure upon thetreadle 1 6 when .the 4operator presses it to turn the cams 14 and lift the pad carrier into engagement with the lasted shoe.

The twin cams 14 are provided with a'.

spring 18 which cushions the backward movement of the 'cams when' the pfad 'carrier is allowed to drop. Eachpad-carrier is given 'a .positive upward movement by means of a power actuated toggle, the. upper arm 19 of which `carriesa rollerclutch, in-

justed, changing the angle between .the .up-4

per and lowertoggle leverevand consequently varying the amount of upward thrust ofthe toggle drm 19, The power' driven mechanism by which the link 21 is reciprocated. to move the toggle is the same as that disclosed inthe patent to Davenport above been moved either upwardly or downwardly the power is automatically thrown ot and the link`19 held ineither its extreme uppermostor lowermost position until thehand' lever 27- is again moved by the operator..

Referring'to'Figs. Band 4 for amore dethereto twin bars 28 which' arespaced-.apart sufficiently to 4allow theft-bar 12 to. move 'freely'bet-ween them. `TheA flipper ends of sides are notched cr recessed at 29 and 30 to 32. Fitted about t-he upper 'ends of 4the bars 2S are two collars 33 and 34 which are tailed description of the roller clutch 20,A the upper end of the toggle arm has' bolted the bars 28 are enlarged and their innerw receive hardened steel wedge pieces 31 and` oppositely bored each to'receive loosely two Y rollers 35 vwhich'eatlend4 across the recesses 29 and 30, the caliber of .the 'bore's being 'slightly larger t-hanhe rolls 4to allow them a certain amount oi loose lay.2 ;Elhe rolls 35 are removably secured 1n plaie by the enlarged heads 36' andcotter -pin s' "3 7 `The collars are norm'all Y. -held or pulled downwardly by me'ans o two 'springs 38secured at their lower ends byl pins 39' upon the toggle lever .19 and 4connected to the upper collar 34 through straps 40,- The down'A ward movement/of- -the collarsfi` 'andat under the action'o'f the spring 3S-is li-mitedby the adjustable stops H-Carried upon the frame of the machine. Between-fthe collars 33 and 34, held in suitable recesses,"are the springs 42, \vhich.' are somewhat stronger than the springs A35S- and hold the tw'o collars slightly separated when the collars are held-f' roo downwardly by thesprings 3 8 against the stops 41. Y AWhen the toggle arm 19 is raised, the bars 28 move upwardly "until: the wedge pieces and securely grip ,with awedging-.aotion the bar 12, which is then positively' moved up# stops 41 which limit. the 'downward moye- 'ment of the -collars 33 and 434, the position of the rolls'i-in'thefrecesses maybe va-A Wardly "by the -toggle.\ By-'adjustingthe ried to compensatefor lthe adjustment. of. j

Kthe toggle actuating link 21, to compensate for wear on the clutching parts, or. to "allow-- any desired Aamount ofslr'p between the bars.

28 and 1 2 before the rolls 35 shall' be brought into their wedging engagement.. The collars 33"and 34 are'normally slightly semi rated bv the springs 42 Ato, allow them slightdegree of .motion independently of each other,- so that if .the Set of rolls held -by one collar engages the bar 12 before the set o .rol-ls held bythe other collar.

Yindependent movement of theA latter'rollarvio also 'throw onthe .clutch vwhich releases the sole pressing pa-d in the other press and allows it to, drop for the removal of the work. This in reality reduces the numberV of '.nio-

tions which the operator Amust malte to actu.

atethe,` machine'in pressing a single sole to .two motions, 'first' depressing v,the pedal A16A to raise the'pressingl pad into engagementl With' the shoe, and second moving the shipper lever 327V' to *give the coiiipre'ssion stroke, vthe sole' .pressing Apad being releasedand dropped :troni the work by the movement'` which the operator gives to the shipper le- Aver 27to cause the sole compression stroke on the opposite half of the machine.

In: laying the soles on diteieiit'classes of "1-A sole pressing machine, having, .'oombinatioii, a fixed )ack forv lasted shoe, a movable sole s being normalljv drawn a way ,shoeslit is desirable that the amount of compression maybe variedl from' that re-' quired in'heavy mens shoes to that.' required inthe lighter ivoiiieiis shoes. Provisionfor this is made by the adj ustnieiit of the link 2l which allows the length of the sole `laying stroke ofthe toggle to be varied according .to the character ofthe work.

Tlie'niachine iii-"which my. invention is shown as embodied lhas the shoe-supporting jack uppermost and the pressing pad movable upwardly -into engagement therewith.
